基于环分析的飞机结构件槽特征腹板精加工区域自动创建方法

摘要/Abstract

摘要：

针对飞机结构件腹板精加工区域创建中曲线裁剪的分类情况多、裁剪后线段取舍判断复杂且易出错的问题，提出了基于环分析的腹板精加工区域自动创建方法。将各种飞机结构件槽特征的广义侧面与广义底面外环边界投影至腹板面，将投影曲线段离散成一系列直线段并对其求交分割，采用直线段旋转法进行环分析，进而创建最优化的腹板精加工区域。对闭角、开闭角并存及共侧面等类型的槽特征腹板加工区域创建进行统一计算，算法通用性好，有效地提高了腹板精加工编程的效率。基于以上研究开发的基于特征的腹板精加工数控编程系统已在某大型航空制造企业中得到良好的应用。

Abstract:

A loop-analysis-based method was proposed to address the problem concerning the variety of curve-clipping types, the complexity of accepting or deserting the clipped curves and the error-prone characteristics of creating bottom finishing region of pocket feature in aircraft structural parts. In this method, the boundary of exterior loop of the generalized sides and generalized bottoms of the part were projected to the bottom. Then these curves were discretized to a set of lines. After that,
the lines were tailored with the calculation of all the intersections. Ultimately, using the line-rotating method to analyze the loop and the optimized bottom finish machining region was obtained. This method can improve the efficiency of NC programming for bottom finish machining effectively, and bottom finish machining region of all kinds of pocket feature can be created using this method. Based on the above research, a feature-based bottom NC programming system was developed, which is applied in a large aviation manufacturing enterprise successfully.

Key words: loop, aircraft structural part, pocket feature, bottom, machining region
